Ice cream mold



IN VENTOR l AORNEYS F, BAXTER ICE CREAM MOLD May 22, 1956 Filed Oct. 6. 1954 United States Patent() i .2,746,402 ICE MLD Eloy Baxter, ;Fort Lauderdale, 1T-la. Application AOctober f6, vv11954, Serial No. 460,5684 `mclsims.- (cl. 10J-19.)

` refrigerators. v`rThe mold is of thetype comprising a plurali-ty offconcentrically disposedtubular molding members. 'In use, `the Jspace' between lthe outermost two of these tubular molding members :is filled with ice cream of kone type "or'color, the ice cream is caused to congeal,

Athe inner moldrnember "is withdrawn, andthe interior fspace defined by` `the vcongealedfice cream is then ffilled with 'ice Vcream of a'diferent type for color, which .'is in turn 'caused to congeal.

My 'improved 'mold is 'characterized by provision 'of at :least two tubular mold :members of substantially diiterent diameters/and associated end .closures so iconstructed Vthat the mold" members jmay be lmoreV readily uassembled to'receive the initial quantity of ice cream mix, l and that the inner' mold member, lor members, may be more readilywithdrawn after 'the' initial charge of ice cream has been congealed.

In order that the invention may be understood in detail, reference is 'had' tothe accompanying drawings which form ia part Aof 'this specifica-tion, and wherein 1 Figui isan exploded perspective :View of an `rice lcream mold `'constructed `in accordance Lwith l.one embodiment of the invention;

Fig. 2 is .a vertical sectional view of the mold .olf Eig. l :showing fthe mold fully assembled and with the `outmost mold chamber filled with icecream;

Fig. 3 is a vertical sectional view ,similar to Fig. 2 but with one end closure and the inner mold member re- ".moved; and' l Y Figs. 4-6 are fragmentary vertical sectional views illustrating modified end closures constructed in accordance with the invention.

lReferring now to the drawings in detail, and first to Figs. l-3 thereof, it will be seen that the embodiment of the invention here illustrated comprises an outer` cylindrical casing member 1 inthe form of an openended tube, a similar inner forming member 2 of smaller diameter than the outer member 1, and a pair of end "closures 3 and 4 constructed to close the ends of members 1 and 2 and support said members in concentrically disposed relation. It will be noted that the members 1 and 2 are of substantially equal length and provide substantially uninterrupted plane cylindrical molding surfaces extending continuously between the two end closures.

The end closure 3, which may be termed the bottom of the assembled device, includes a circular end plate 5 having an outer annular flange 6 of such diameter as to closely embrace one end of the casing member v1 in friction-fit relation, as seeny in Figs. 2 and 3. The closure 3 `is also provided with an inner annular flange 7 of such 2,746,402 Patented May 221,4 1956 ICC diameter as 'to iit snugly within 'oneend of "the forming memberZ, as seen .in Fig. 2.

At `the 'opposite end of the assembly, the end closure y4 is provided with a circular end plate l8 having an outer annular 'flange 9, o'f msuch diameter as to snugly embrace the end ofthe casing member 1, and also an` inner annular liange 10 o'f such .diameter as to fit snugly within 'the end of the inner 'forming member 2.` I'hus, the members 1 and f2 are held rigidly in coaxial yrelation .by Laction of the pairs o'f'iianges'jd, 7 and .9 I0, .the anges being themselves coariial'lyndisposed on their respective end plates .5 and 8.

It will be noted that, .wliile the `outer flanges 6 and L9 are of substantially .the same length, theinner .flange 7 'on end plate 5 is made much shorter than ,the outer flanges. The inner ange 10, on the other hand, is much longer than the outer anges. Thus, when the mold is fully assembled, the inner member 2 .iisfirmly ,positioned by "reason of the relativelygreat supporting Asurface ,provided -jointly b y 'flanges 7 and 10. `B.ut when ,the .end `closure 4 is removed, the inner forming member 2 Amay be easily worked -free of the' shorter lange 17,. I

` Tolm'ake -possible ready withdrawal Ao'f the ,inneriorming `member 2 after the ice crea-m 11 "has hardened, the member ,2 is provided at the end engaged by .closure 4 with a .pivoted bail 12 which issem'i-circular Vin form. As seen in Fig 2, the ends of the bail 12 areppivoted on the member 2 by .suitable studs .and .the radius `of .the bail is such that the bail may be swung .to a :retracted position 'in which it engages the surface of member .2 lopposite 'that engaged .by ,the .'angelli). In such .retracted position, the ba'i1'12 flieswith `its uppermost edge llush with the corresponding end of fhemember 2, so that the closure 4 may be applied with yplate 8 ,in full engagement with the lend .surfaces nf `members 1 and ,2. As seen [in Fig. 1 Athe bail 12 may lbe swung to ian outer position .in which -it may 'be easily grasped by .fthe user.

As seen in Figs. 1 3, the end `closure 4 is .preferably secured in place by .means of partial threads 13 and 14 formed by a pressing operation fin the members 1 ,and 9, respectively. securing means .may be provided for the end closure In use, the end closure 3 lis jrst placed .on the `casing member 1. The -inner vforming,mernberl,is .then inserted within the casing and seated fully on the linner flange .7 of the .closure 3. Ihe .12 .is pivoted .to retracted .position. The space between member 2 .and casing 1 is then filled with ice cream mix, .as at 11, Eig. 2., ,and the end .closure 4 then applied so that the flanges 9 land '10 are fully seated, as sbown. The .mold is then `,placed in the 'freezer until the ice cream 11 has fully congealed,

after which the mold is taken out and the closure 4 is removed. The bail 12 is then raised and the member 2 worked free from the flange 7 by a twisting and pulling motion, the member 2 then being fully withdrawn, leaving a cylindrical cavity defined by the congealed ice cream 11, Fig. 3. This cavity is then filled with ice cream of a different kind or color, the closure 4replaced, and the mold replaced in the freezer to complete the freezing operation. The mold is then again removed, held under running water for a few moments to free the casing 1 from the ice cream, and the completed composite ice cream bar removed.

Mold members 1 and v2 may be fabricated from metal, synthetic resin or other suitable material capable of providing a firm, smooth, tubular molding surface. While I have illustrated a particularly advantageous embodiment of the invention wherein the mold members 1 and 2 are of circular cross-section, it is to be understood that these tubular members, and the cooperating closure flanges 6,

. 7 and 9, 10, may have a non-circular cross-section. It

3 is highly advantageous, however, to employ a cylindrical inner mold member 2 and cylindrical ange 7lin order that the member 2 may riore readily be worked free vfrom that flange by ya slight rotary or twisting movement imparted by useof the bail 12. v

Ingthe embodiment of Figs. .1-3, the flanges 7 and 10 are in the form of separate cylindrical tubes secured to their respective closure plates in any suitable manner, as by welding. As seen in Figs. 4e6, these llanges may be formed integrally with the end plates 5 and 8. Thus, in Fig. 4, the flange a is double-walled. ln Fig. 5,.the end plate 8al is4 pressed to provide a central convex portion 8b connected to the mainend plate by the flange 10b. And, in Fig. 6, the construction is similar to that of Fig. 5, except that the central portion 8c .is flat. It will be obvious that many such modifications may be made in the end closures, both as manufacturing expedients and to provide special configurations in the ends of the iinished ice cream bar.
